For example, say you want to swap out your startup drive for a much faster SSD with a 512 MB capacity—enough to hold all your current data and allow for future growth. The easy solution is to move your home folder to a different drive.
How to Move Your Home Folder to a New Location

At this point, you should make sure everything is working as it should. One way to do this is by creating a test file in TextEdit and saving it to your new Home folder.
